Discovery Semiconductors introduces its narrowband optical receiver for RF-over-fiber applications, covering a frequency range of 54 to 67 GHz. This device can generate a linear RF output power of up to -10 dBm, or 200 mV peak-to-peak output voltage. It can operate at both 1310 nm and 1550 nm wavelengths. It features 20 dB of power gain and dissipation of less than 200 mW. It also has low ripple amplitude in the device's passband.
This linear narrowband optical receiver provides improved gain, output voltage, and phase stability for photonic links. It will serve various V-band RF-over-fiber market segments that enhance the wireless performance of applications, including wireless systems, microwave RF carrier distribution, and remote antenna interaction.

KBC Networks introduces a new series of broadcast products for complex environments. The KBC product range includes fiber interfaces and digital video splitters, designed to operate in demanding environments.

From their respective headquarters in Caesarea, Israel, and Walldorf, Germany, ColorChip and Molex Incorporated announced on September 29, 2010, the development of the QSFP+ 40G-LR4 pluggable module with a duplex LC interface. The transceiver, whose development was funded by the U.S.-Israel Binational Industrial Research and Development Foundation (BIRD) in 2007, is designed to provide the same performance as the CFP 40G-LR4 module, but with significant advantages for original equipment manufacturers (OEMs) and end users in terms of size, power consumption, and cost.

The Optimux-134/125 provides a simple and economical solution for transporting multiple TDM and Ethernet links over distances of up to 110 kilometers (68 miles).

Avago Technologies introduces the HFBR-3810Z, a short-range 10 MBd fiber optic transceiver/transmitter designed for isolating frequency inverters and power converters in renewable energy installations. In wind and solar farms, fiber optic technology is generally considered the preferred isolation technology for connecting low-voltage control logic or microprocessors to high-voltage power inverters and switching circuits.

One of Avago Technologies is a compact, low-cost, high-bandwidth parallel optical solution for short-distance data interconnection and communication applications. 

Adilec Enginyeria, SL presents for 2010 the new range of MT4 transmitters and MR4 receivers, a 4-channel video multiplexer over a single optical fiber up to 6 km in multimode fiber and 50 km in single-mode fiber, depending on the model.
